THE EYE.
Mules are remarkable for having good eyes. Occasionally they become inflamed and sore. In such cases the application of cold water, and the removing of the cause, whether it be from chafing of the blinders, forcing the blood to the head through the influence of badly fitting collars, or any other cause known, is all I can recommend in their case.
THE TONGUE.
Mules suffer much from injury to the tongue, caused by the bad treatment of those who have charge of them, and also from sore month, produced in the same manner. The best thing for this is a light decoction of white-oak bark, applied with a sponge to the sore parts. Charcoal, mixed in water, and applied in the same manner, is good. Any quantity of this can be used, as it is not dangerous. If possible, give the animal nourishing gruels, or bran mashes; and, above all, keep the bit out of the mouth until it is perfectly healed.
POLL-EVIL.
This is a disease the mule more than all other animals is subject to. This is more particularly so with those brought into the service of the Government unbroken. It will be very easily seen that the necessary course of training, halter-breaking, &c., will expose them to many of the causes of this disease. Aside from this, the inhuman treatment of teamsters, and others who have charge of them, frequently produces it in its worst form. It begins with an ulcer or sore at the junction where the head and neck join; and from its position, more than any other cause, is very difficult to heal. The first thing to be done, when the swelling appears, is to use hot fomentations. If these are not at hand, use cold water frequently. Keep the bridle and halter from the parts. In case inflammation cannot be abated, and ulceration takes place, the only means to effect a cure, with safety and certainty, is by the use of the seton. This should be applied only by a hand well skilled in the use of it. The person should also well understand the anatomy of the parts, as injuries committed with the seton-needle, in those parts, are often more serious and more difficult of cure than the disease caused by the first injury.
FISTULA.
This is a disease the mule is more subject to than any other animal in Government use. And this, on account of his being used as a beast of burden by almost all nations and classes of people, and because he is the worst cared for. Fistula is the result of a bruise. Some animals have been known to produce it by rolling on stones and other hard substances. It generally makes its appearance first in the way of a rise or swelling where the saddle has been allowed to press too hard on the withers, and especially when the animal has high and lean ones. As the animal becomes reduced in flesh, the withers, as a matter of course, are more exposed and appear higher, on account of the muscle wasting from each side of the back-bone. This, under the saddle, can be remedied to a great extent, by adding an additional fold to the saddle blanket, or in making the pad of the saddle high enough to keep it from the withers. In packing with the pack-saddle this is more difficult, as the weight is generally a dead, heavy substance, and as the animal steps low or high, the pack does the same. Much, however, might be done by care in packing, to prevent injury to the withers and bruising of the back-bone. When the withers begin to swell and inflammation sets in, or a tumor begins to form, the whole may be driven away and the fistula scattered or avoided by frequent or almost constant applications of cold water--the same as is recommended in poll-evil. But if, in despite of this, the swelling should continue or become larger, warm fomentations, poultices, and stimulating embrocations should be applied, in order to bring the protuberance to its full formation as soon as possible. When full, a seton should be passed, by a skillful hand, from the top to the bottom of the tumor, so that all the pus may have free access of escape. The incision should be kept free until all the matter has escaped and the wound shows signs of healing. The after treatment must be similar to that recommended in the case of poll-evil. The above treatment, if properly administered, will in nearly all cases of fistula effect a cure.
COLLAR-GALLS.
Sore necks, saddle-galls, and stilfasts, are a species of injury and sore, which are in many cases very difficult of cure, especially saddle-galls on mules that have to be ridden every day. One of the best remedies for saddle gall is to heighten the saddle up as much as possible, and bathe the back with cold water as often as an opportunity affords. In many cases this will drive the fever away and scatter the trouble that is about to take place. This, however, does not always scatter, for the trouble will often continue, a root forming in the center of what we call the saddle-gall. The edges of this will be clear, and the stilfast hold only by the root. I have had many cases of this kind occur with the mule, both on his back and neck, mostly caused on the latter part by the collar being too loose. And I have found but one way to effectually cure them. Some persons advise cutting, which I think is too tedious and painful to the animal. My advice is to take a pair of pincers, or forceps of any kind, and pull it out. This done, bathe frequently with cold water, and keep the collar or saddle as much free of the sore as possible. This will do more towards relieving the animal and healing the injury than all the medicine you can give. A little soothing oil, or grease free from salt, may be rubbed lightly on the parts as they begin to heal. This is a very simple but effective remedy.
